In ""Full Duplex Active Cancellation for wireless communication and co-exisTence"" (FUDACT) we explore a set of new co-existence technologies culminating in a new radio transmission paradigm to improve spectrum efficiency. The FUDACT goal is to support two Europe 2020 flagship initiatives: Digital agenda for Europe by addressing some of the H2020 Future Internet challenges and Innovation Union by paving the way to innovation-friendly environment.
FUDACT aims at a fundamental understanding of limitations of active self-cancellation techniques under conditions of simultaneous transmission and reception in close or overlapping frequency bands. The project's primary goal is to deliver a solution for a shared antenna system capable of cancelling at least a 1W transmitter (densely deployed small cells in wireless infrastructure) in the receive band, a great research challenge advancing the state of the art by at least 2 orders of magnitude. To accomplish these ambitious goals we will be pursuing the following closely related objectives: (1) Determine the technology limits of active cancellation of self-interference in wireless transceivers (2) Demonstrate an architecture capable of cancelling a +23dBm transmitter and a 0dBm of narrowband blocker (3) Investigate mixer-first receiver architectures capable of tolerating higher blocker signal levels (4) Apply the techniques (1-3) in the design of a full duplex future-oriented wireless communication network."
